Oh, wow. That's a demo I'm going to try, definitely!
It looks really promising.

It's an instant purchase for me anyway, but I'm happy that I can play the demo now. Counting the days till the release! :-)

I think I'm in love!

Everything about that gameplay trailer seduced me! :) It's moments like these that make me appreciate a demo. Thx GOG!

Let me get this straight: that demo is 10,8 GB (!), or the final game will be?

The installer at least clocks in at slightly above 10GB.

If you accept the demo, then are you stuck having that attached to your GOG account forever?

I would think so, but I don't know if one later buys the full game, then if the demo entry merges into the full game's entry. I haven't got any demo.

They don't get merged, the demo entry stays.

I love demos so I have a lot of them here, after downloading them I just hide the entry. But it would be nice if we could get better options for organizing our games on the website.

That's terrible. GOG should make an option so that all customers can easily permanently delete demos off of their account with one click.

Until then, it seems best to avoid demos on GOG since they can't be deleted off of your account.

That's true. If one buys that demo's full game, then the demo entry doesn't have a reason to exist in the library! But then again we go into the long discussion of why we can't have something erased from our libraries...

Once installed, Shadow Gambit demo uses 15 GiB of storage space.

I've just completed the demo (over 3 hours of gameplay!) and I have to admit - Mimimi have exceeded my expectations by far! Shadow Tactics and Desperados III are two of my most beloved games and Shadow Gambit is a huge step forward, which I thought would be impossible.

The characters, setting, storyline, music, maps - marvelous! And the ship design! I'm in total awe what Mimimi created and I can't recommend it highly enough - please try out the new Stealth Strategy game. Bravo, Mimimi!

There have been demos that present levels that were excluded from the main game, other times the demo level was present but significantly altered. (I remember one case where the demo was a tough challenge and the game's level had enemy's hp and placement changed to become a walk in the park.)

In those cases it'd be a pity to see the demo disappear.

Unfortunately I don't remember any specific case off the top of my head.

With that said, I agree that the user should be able to have demos and even games they regret purchasing removed from their libraries.
